Product Code:SAE J1165
Title:Reporting Cleanliness Levels of Hydraulic Fluids
Issuing Committee:Cttc C1, Hydraulic Systems
Scope: This SAE Recommended Practice has been formulated to advance and endorse the use of the ISO (International Organization for standardization) Solid Contaminant Code as the universal means for expressing the level of particulate contaminant in hydraulic fluid and for specifying acceptable limits of cleanliness. Worldwide approval was gained for this coding system because it provides a simple, unmistakable, meaningful, and consistent means of communication between suppliers and users. The code applies to all types of hydraulic (liquid) fluids used in fluid power and control systems as applied to self-propelled machines as referenced in J1116. The purpose of this recommended practice is to provide a practical and uniform method for graphically representing the contamination level of a fluid and assigning its proper ISO cleanliness code. Although the approval code is explicit and offers no opportunity for misinterpretation, flexibility in application is provided to satisfy the customs of the cooperating nations. This practice is intended to facilitate the use of the ISO code and encourage its promulgation throughout the industry.

Title:Composite Fuel Tanks, Fuel System Design Considerations
Issuing Committee:Ae-5 Aerospace Fuel, Oil And Oxidizer Systems Committee
Scope: 1. SCOPEThis AIR is a compilation of engineering references and data useful to the technical community that can be used to ensure fuel system compatibility with composite structure. This AIR is not a complete detailed design guide and is not intended to satisfy all potential fuel system applications. Extensive research, design and development is required for each individual application. 1.1 PurposeThis document is intended to serve as guidance to airframe and equipment manufacturers for the design and installation of fuel systems into composite structure. This document is not intended to be a fully definitive specification, but concentrates on areas where it is felt guidance is needed. The purpose of this AIR is to compile one definitive source of the references, rules, regulations and preferred practices for the development of a fuel system in composite structure. This AIR sets forth some useful design considerations for work with composites as it relates to the fuel system.1.2 BackgroundThe development and installation of a fuel system in composite structure introduces a variety of design situations which are different from aluminium. The differences are related to the properties of the composite material. As an example these may include low electrical and thermal conductivity, greater design sensitivity to holes, reduced shielding from electromagnetic radiation, reduced conductivity of lightning and potential corrosion in graphite aluminum interfaces.1.3 Field of ApplicationThis AIR applies to the aerospace industry and specifically to aircraft that use common petroleum fuels.
